Weird gear shift sqeeking noise

[Defratos]

Hey guys, hope someone could help me out here. For some odd reason I've been getting weird sqeeking noises from my gear shift especially when changing from 2nd to 3rd and 4th. I hear it most when I shift very slow. I vaccumed inside the shift a few weeks back and though I might have taken some greese out so I greesed the shift (Where the ball mount meets up) but there's still a sqeeking noise, know any other solution? more greese?
